Trijicon ACOG 4×32 Tritium Riflescope .223/5.56 BDC Amber Crosshair Reticle FDE

Features

  • Tritium‑Only Illumination (Battery‑Free): Reticle appears black in bright light; center glows amber in low/no‑light via tritium phosphor lamp—no fiber optic, no batteries to manage.
  • 4× Fixed Combat Optic: Compact prism design delivers rugged, repeatable 4× magnification for enhanced ID and hit probability on 5.56/.223 carbines to 600 m.
  • .223/5.56 BDC Amber Crosshair Reticle: Ranging / drop stadia calibrated for 5.56 NATO trajectories; center‑illuminated crosshair aids precise holds when zeroed at 100 m.
  • Forged Aluminum Duty Housing (FDE Finish): Single‑piece 7075‑T6 alloy body with Cerakote‑style Flat Dark Earth coating; shock‑, impact‑, and field‑hard for service use.
  • Waterproof to 100 m & Fog‑Proof (Dry‑Nitrogen Filled): Exceeds typical MIL requirements; sealed system resists water intrusion and internal fogging.
  • External Capped Adjusters: Windage/elevation under tethered caps; 2 clicks/inch @ 100 yd (½ MOA) for zeroing.
  • Backup Iron Sights & TA51 Flattop Mount Included: Integrated BUIS provide tertiary aiming; thumbscrew Picatinny adapter ships ready to install.
  • Both‑Eyes‑Open Usability: Although not a fiber BAC model, the generous FOV and ACOG sighting concept support rapid engagements with practice.
  • Made in USA & Trijicon Warranty.
